This is the firm's "Challenge" microscope, with a dark brass, claw foot. It differs from the Ross model microscopes Swift made earlier. Instead of the vertical pillars that supported the limb, the curved foot holds the limb on trunnions. The Wenham binocular body moves on the rack and pinion and has an ocular adjustment mechanism (with a single knob) on the back. It comes with a wooden carrying case and accessories.
